Description

Deduction method and device

TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a charging method and apparatus. BACKGROUND In the field of intelligent networks, an Online Charging System (OCS) is the most widely used charging system framework. The charging system framework separates call access and charging control, and can be controlled in real time. User credit, reduce arrears, reduce bad debt costs, and effectively control operational risks. The interaction between the call access and the charging control is mainly through the Diameter Credit Control (DCC) interface message and the Man-Machine Language (MML) interface message. The Diameter protocol has the advantages of high reliability and good failure mechanism, and is mainly applied to a prepaid Paid Service (PPS) system. The MML interface message has the advantages of easy understanding and simple message interaction, and is mainly applied to an Interactive Voice Response (IVR) system. The current PPS system mainly handles the function of the user to make a call, and completes the real-time charging requirement of the user call. The IVR system mainly provides users with a series of services such as recharge, check balance, transfer, family number management, brand management, connection to a third party or operator. Among these services, services such as top-up, check balance, transfer, etc. are usually free for users. The management of family number, brand management and other services use the method of pay-per-view. The user charges a change every time a change is made. Such billing can be easily solved through the MML interface. Connecting third parties or operators is a special service. The operating cost is higher than the previous two services, and if the user spends more time, the consumption is higher. For these services, it tends to be longer. Real-time billing, which can better avoid malicious use of third-party or operator resources, and effectively reduce costs. In order to better complete the real-time charging function according to the duration in the IVR system, it is necessary to complete a set of DCC message processing charging logic and abnormal control flow in the IVR system. 1 is a flowchart of a charging operation of an IVR system according to the related art. As shown in FIG. 1, the flow includes the following steps (step S102 - step S134): Step S102, a user initiates a call, and a mobile switching center (Mobile Switch Center, Referred to as MSC), the IVR service on the Service Control Point (SCP) is triggered according to the Originating CAMEL Subscription Information (O CSI). Step S104: After the MVR message is successfully authenticated by the MML message to the OCS side, the request report BCSM Event (abbreviated as RRBE) and the Connect To Resource (CTR) message are used to establish a playback connection with the MSC. . Step SI 06, after the connection of the playback is successfully established, the IVR service plays the main menu for the user through a Prompt And Collect User Information (P&C) message. Step S108, the MSC returns the user's input through P&C_res. Step S110: After receiving the response from the user, the IVR service analyzes the function corresponding to the button input by the user, and finds that the third party or the attendant function is connected, and then sends a Disconnect Forward Connect (DFC) message to cut off the playback. Resource connection. In step S112, the IVR service performs the call authentication of the connected operator to the OCS side through the initial CCR message (CCRJNITIAL) message, and applies for the time slice. Step S114, the OCS returns the duration of the time slice of the call by responding to the message CCA_INITIAL message. In step S116, the JVR service delivers the RRBE, the application charging (Apply Charge, AC for short), and the CO NECT message to the third party or the attendant. Step S118, the MSC notifies the IVR service to connect with the third party or the attendant is successful through an event report (BCS, ERB for short) message. Step S120, the MSC notifies the message through an Apply Charging Report (ACR) message.

In the IVR service, the first time slice has ended the call. Step S122: The IVR service sends a second time slice request to the OCS side through a CCR update message (CCRJJPDATE) message. Step S124, the OCS returns the duration of the second time slice by using the response message CCA_UPDATE. Step S126: The IVR service sends an AC, and notifies the MSC to continue the call. Step S128, after the user calls the attendant, the MSC returns the time of connecting the third party or the attendant through the ACR and the ERB message, and notifies the end of the service call. Step S130, the IVR service sends an end CCR message according to the duration reported by the MSC.

(CCR TERMINAL), notify OCS to deduct the fee. In step S132, the OCS returns the deduction result by the response message CCA_TERMINAL. In step S134, the IVR service delivers the RC to end the entire call. As can be seen from the above process, from step S116 to step S134, these steps are a complete step of processing a call, and the IVR system performs the real-time deduction function of calling a third party in the above manner, which may cause the processing logic of the IVR system to be complicated.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. In the related art, when the IVR system performs the deduction process of the called party (which may also be called a third party or an attendant, etc.), if the call and deduction steps are performed by the IVR system, the processing logic will be complicated, and the wave More resources. Based on this, an embodiment of the present invention provides a method and device for charging. The details will be described below by way of examples. The embodiment provides a deduction method, as shown in the flowchart of the deduction method shown in FIG. 2, the method includes the following steps (step S202 - step S204): Step S202, the PPS system receives the IVR system to access the above The call of the PPS system; Step S204, the PPS system applies for a charge to the online charging system according to the duration of the session when the session of the call ends. Through the above method, the access call and the deduction operation are handled by the PPS system, and the IVR system connects the call to the PPS system, and then the PPS system applies to the online charging system according to the duration of the session when the session of the call ends. The deduction fee solves the complicated problem of the deduction operation of the IVR system in the related art, thereby simplifying the processing logic and the processing flow, reducing the amount of code, and reducing the waste of development resources.

When the IVR system accesses the call to the PPS system, the information related to the call needs to be sent to the PPS system, so that the PPS system performs the subsequent operation process. Therefore, this embodiment provides a preferred implementation manner, that is, the PPS system receives the IVR system. The call to be accessed to the PPS system includes: The IVR system replaces the service key information with the service key information of the PPS system, and replaces the access number of the called party with the called number of the PPS system; the PPS system receives the IVR system to send The above-mentioned service key information after replacement, and the above-mentioned called number after replacement; the PPS system is connected to the called party. When the access number of the called party is replaced, the number attribute is generally set to the domestic attribute, because the operator's number is generally the domestic number. If the configuration is not the domestic number format, the conversion can be performed according to the following rules: The configuration format is a domestic number format, and the IVR system sets the attribute value of the access number to the domestic number; if the configuration format of the access number is the country code + number format, the IVR system sets the attribute value of the access number to the international number. If the configuration format of the access number is 00+country code+number format, the IVR system sets the attribute value of the access number to unknown, or the IVR system modifies the configuration format of the access number to the country code+number format. , and then set the attribute value of the above access number to an international number. After the IVR system accesses the PPS system, the IVR system is processed. Since the data area of the IVR system has been released when accessing the PPS system, the IVR system has no way to monitor the completion of the PPS system, so the access is In the PPS system, the IVR system needs to record the time of accessing the PPS system, the connected third party or the operator's number, and the calling number into the generated CDR bill. When an abnormality occurs in the OCS charging system, You can use the start time in the CDR recorded by the IVR system, the calling number, the connected third party or the operator's number (equivalent to the called number in the PPS system CDR), for the PPS system. Sorting is performed separately. When the IVR system call is found, the caller's call bill is called, and the offline deduction is completed to minimize the loss. Based on the above-mentioned CDR recording process, the present embodiment provides a preferred implementation manner, that is, after the PPS system receives the service key information sent by the IVR system and the access number of the called party of the call, the method further includes: an IVR system The acquisition time of the above call, the access number of the called party, and the calling party number are included in the CDR bill.

The process of connecting the called party to the called party is basically similar to the process of connecting the called party to the IVR system. The execution subject is converted from the IVR system to the PPS system. The following describes the process of connecting the called party to the PPS system. The PPS system is connected to the called party. The PPS system requests the OCS side to access the call authentication of the called party, and applies for accessing a time slice of the called party; the PPS system receives the duration of the time slice returned by the OCS side; The MSC sends a connection message, where the connection message is used to indicate that the called party is connected; and the PPS system receives the message that the MSC returns the access to the called party successfully.

After the PPS system is connected to the called party, the method further includes: after receiving the call of the current time slice fed back by the MSC, the PPS system applies for the next time slice to the OCS side; and the PPS system receives the foregoing return of the OCS side. The duration of a time slice; the PPS system sends a notification message to the MSC, wherein the notification message is used to notify the MSC to continue performing the call operation; and the PPS system receives the notification of the end of the session of the call returned by the MSC and the duration of the session. After the PPS system is connected to the called party, the PPS system needs to apply for a deduction to the online charging system. Specifically, the PPS system applies for a deduction to the online charging system according to the duration of the session: the PPS system returns the session according to the foregoing MSC. The time limit is sent to the OCS side, and the deduction instruction message is used to indicate that the OCS side performs the deduction operation; and the PPS system receives the deduction result of the OCS side feedback. Both the IVR system and the PPS system are active and are on the same service control point SCP platform. The implementation process of the above embodiment will be described in detail below in conjunction with the preferred embodiments and the accompanying drawings. In this embodiment, when the IVR system is integrated with the PPS system, when accessing a third party or an attendant, the IVR system cannot achieve a good time-based billing. FIG. 3 is a signaling flowchart of time-based charging when a user accesses an attendant according to an embodiment of the present invention. As shown in FIG. 3, the process includes the following steps (step S302-step S336): Step S302, the user initiates a call, The MSC triggers the service according to the 0_CSI. After the SCP receives the IDP message, the IVR system determines that the called number is the management access code and enters the IVR management process. In step S304, the IVR system sends an RRBE (O ABANDON, the caller gives up), and the CTR connects to the MSC. Step S306, the IVR system plays the main menu for the user through the P&C message. Step S308, the MSC returns the user's input through P&C_res. In step S310, the IVR system analyzes the function corresponding to the button input by the user, and finds that it is a third party or an attendant function, and then sends a DFC message, disconnects the playback resource, and prepares to connect the operator. Step S312, the IVR system needs the third party or operator number of the access code and the service key of the PPS system to be transmitted to the signaling conversion module. The signaling conversion module deletes the data area occupied by the IVR service, and then copies the IDP message received in step 201, and replaces the service key in the copied IDP message with the service key of the PPS, and the called number is replaced. For the number of the attendant to be accessed, the other parameters remain unchanged, and the message is sent in the form of an initial session message. At this time, the PPS service of the same SCP platform receives the message for subsequent processing. The IDP message generated in this step has no new session number compared to the general message. The session number is extended to the session number of step 201, and the IDP is invisible externally and is an internal message. In this step, when the called number is replaced, the number attribute is generally set to the domestic attribute, because the operator's number is generally the domestic number. If the configuration is not the domestic number format, the conversion can be performed according to the following rules: The operator number format is configured as In the domestic number format, the number attribute value is set to the domestic number. When the operator number format is configured as the country code + number format, the number attribute value is set to the international number. When the operator number format is configured in the format of 00+country code+number, the number attribute value is set to unknown, or it is normalized on the IVR service side, 00 is removed, and the number attribute value is set to international. Step S314, the PPS system performs call authentication for connecting the attendant to the OCS side through the initial CCR message (CCR_INITIAL) message, and applies for a time slice. Step S316, the OCS returns the duration of the time slice of the call by responding to the message CCAJNITIAL message. Step S318, the PPS system sends an RRBE, an application charging (AC), a CONTINUE message to connect to a third party or an attendant. Note that the CONTINUE message is sent here because the called number received by the PPS system is the number that needs to be connected. In step S320, the MSC informs the PPS system to connect with the third party or the attendant is successful through the ERB (o_answer) message. Step S322, the MSC notifies the PPS system through the ACR message that the first time slice has ended the call. Step S324, the PPS system sends a second time slice request to the OCS side through a CCR update message (CCRJJPDATE) message. Step S326, the OCS returns the duration of the second time slice by responding to the message CCA_UPDATE. Step S328, the PPS system sends an AC, and notifies the MSC to continue the call. Step S330, after the user calls the attendant, the MSC returns the time of connecting the third party or the attendant through the ACR and the ERB message, and notifies the end of the service call. Step S332, the PPS system sends an end CCR message (CCR TERMINAL) according to the duration reported by the MSC, and notifies the OCS to perform the deduction. In step S334, the OCS returns the deduction result by the response message CCA_TERMINAL. Step S336, the PPS system sends an RC to end the entire call. The implementation process of this embodiment has fewer modifications to the IVR system, and the method provided by the embodiment is simpler and smaller than the traditional deduction method, and fully utilizes the characteristics of the PPS system and the IVR system. Corresponding to the above deduction method, the embodiment provides a deduction device, which is used to implement the above embodiment. FIG. 4 is a structural block diagram of a charging device according to an embodiment of the present invention. As shown in FIG. 4, the device includes: a call obtaining module 10 and a charge application module 20. The structure will be described below.

The charge application module 20 is connected to the call acquisition module 10, and is set to be online according to the duration of the session at the end of the session of the call. The billing system applies for a deduction. Through the above device, the access call and the chargeback operation are handled by the PPS system, and the IVR system accesses the call to the PPS system, and then the PPS system goes to the online charging system according to the duration of the session at the end of the session of the call. Applying the deduction fee solves the complicated problem of the deduction operation of the IVR system in the related technology, thereby simplifying the processing logic and processing flow, reducing the amount of code, and reducing the waste of development resources.

When the IVR system accesses the call to the PPS system, the related information of the call needs to be sent to the PPS system, so that the PPS system performs the subsequent operation process. Therefore, this embodiment provides a preferred implementation manner, and FIG. 5 is a preferred embodiment according to the present invention.

The structure will be described below. The receiving unit 12 is configured to receive the replaced service key information sent by the IVR system, and the replaced called number; the connecting unit 14 is connected to the receiving unit 12 and configured to connect to the called party. When the access number of the called party is replaced, the number attribute is generally set to the domestic attribute, because the operator's number is generally the domestic number. If the configuration is not the domestic number format, the conversion can be performed according to certain rules. Therefore, this embodiment provides a preferred implementation manner, that is, in the case that the configuration format of the access number is a domestic number format, the IVR system sets the attribute value of the access number to a domestic number; In the case where the configuration format is the country code + number format, the IVR system sets the attribute value of the access number to an international number; in the case where the configuration format of the access number is 00+country code+number format, the IVR system The attribute value of the access number is set to be unknown, or the IVR system modifies the configuration format of the access number to the country code + number format, and then sets the attribute value of the access number to the international number.

The process of connecting the called party to the PPS system is basically similar to the process of connecting the called party to the IVR system, except that the execution subject is converted from the IVR system to the PPS system. Therefore, the embodiment provides a preferred implementation manner, that is, the connecting unit 18 includes: an application subunit, configured to request access to the call party of the called party to the OCS side, and apply to access the called party. a time slot; a time receiving subunit, configured to receive the duration of the time slice returned by the OCS side; a message sending subunit, configured to send a connection message to the MSC, where the connection message is used to indicate that the called party is connected The message receiving unit is configured to receive a message that the foregoing MSC returns to access the called party successfully.

In this embodiment, the IVR system is integrated with the PPS system through the signaling conversion module, and when the third-party or the attendant is not well implemented in the IVR system, the problem of charging by the time is not well realized. The operation of the embodiment is simple, and the modification of the IVR system is less, and the method provided by the embodiment is simpler than the traditional deduction method, and the code amount is small, and the characteristics of the PPS system and the IVR system are fully utilized. In this embodiment, the process of processing the IVR system to transfer the third-party or the attendant's time-based charging by the signaling conversion module is described. FIG. 6 is a network element for charging by the user when the user accesses the operator according to the embodiment of the present invention. The message interaction diagram is as shown in Figure 6. The above-mentioned time-based charging process is as follows: First, the user accesses the IVR system by dialing the IVR access code, and the IVR system authenticates the user and then plays the menu for the user to select. The user selects to access a third party or attendant based on the menu options. In this step, the IVR system obtains the status, brand, and other information of the user through the MML message to the OCS charging system, and uses the information to determine whether the user is allowed to use the IVR service, and which menu to dial to the user. Second, after receiving the user input, the IVR system connects the call to the PPS system. In this step, the IVR system transmits the number of the third party or operator who needs the access code and the service key of the PPS system to the signaling conversion module. The signaling conversion module connects the call to the prepaid PPS system. In this step, the IVR system completes the recording of the CDR and the statistics of the service. Third, when the PPS system is completed, the online charging system is authenticated and applied for a long-term operation, and at the end of the session, according to the duration reported by the MSC, the online charging system is applied for a deduction. In this step, the accessed PPS system is in the same SCP as the IVR system (Service Control

Point, Service Control Point) on the platform, and is active. When accessing the PPS system, the PPS system needs to end the session if it detects that the user's balance is insufficient. If the hang-up message sent by the user is received, the entire session can also be ended. If the user has used the authorized time, he can apply for a new session again to the online charging system. This embodiment mainly generates a virtual IDP message through a signaling conversion module, and needs to access a third party or an attendant in the IVR service, and transmits the number of the third party or the attendant to the PPS service through the IDP message. deal with. The connection and third party or operator's connection and real-time charging requirements are completed by the PPS service.
